Manufacturer Narrative

The affected hose system of type anesthesia set coax was available for investigation.During the analysis at manufacturing site the described problem of a loose inner circuit could not be confirmed.It was found that the outer circuit was loose so that the rotation of the patient connection resulted in a twisting of the inner circuit.As a result of a twisted inner circuit a blockage can occur leading to an increased airway pressure.This is detected by the connected main device and depending on the set alarm limits a corresponding alarm will be posted.Our investigations have shown that the adhesive joint did not conform to specification due to an unstable manufacturing process.A capa was opened to initiate and document further measures.In april 2023, dräger has already informed all customers of potentially affected products about the identified risk with a field safety notice.
